The universe is deteriorating at a faster rate than previously estimated, scientists say, but its ultimate demise remains a distant prospect. The projected disintegration of the last white dwarfs, the dense remnants of dead stars like our sun, is now calculated too occur in approximately 10 to the power of 78 years. This revised estimate is considerably shorter than the earlier figure of 10 to the power of 1,100 years.
Hawking’s Influence Revisited
The updated timeline stems from a study published in May 2025 in the journal Cosmology and astroparticle Physics. A team of Dutch scientists at Radboud University re-evaluated existing calculations based on the theoretical work of British physicist Stephen hawking.
The researchers focused on determining when white dwarfs would cease to exist, utilizing Hawking’s theory of black hole evaporation, proposed in 1974. This theory posits that black holes emit radiation, leading to a gradual loss of mass and eventual disappearance.
Hawking theorized that radiation emitted near a black hole’s event horizon causes particles to fall into the black hole while others escape. The escaping particles, if detected, would indicate that black holes have finite lifespans as they slowly lose energy and shrink.

The Dutch team applied Hawking’s theory to white dwarfs, exploring how these stellar remnants, which can persist for billions of years, eventually dissolve.
“By asking these kinds of questions and examining extreme cases, we want to better understand the theory, and perhaps one day, we will be able to unravel the mystery of Hawking influence,”

While the new estimate of 10 to the power of 78 years for the universe’s end differs considerably from previous calculations, one thing remains clear: Earth, the sun, and the moon will have long ceased to exist by that time.
Earth is projected to become uninhabitable within 1 to 3 billion years due to rising temperatures that will eventually boil away the oceans. Around 5 billion years from now,the sun will expand into a red giant,likely engulfing or destroying Earth. In approximately 6 to 7 billion years, the sun will then transform into a white dwarf, a small, dense, and extremely hot star that will gradually cool and fade over an immense period. The rate of evaporation for any object is directly related to its density.
Regarding the moon, the Dutch scientists estimate it could theoretically take approximately 10 to the power of 89 years to evaporate through a process similar to Hawking radiation. The moon is already slowly drifting away from Earth at a rate of roughly 4 centimeters per year. However, it is more likely that the moon will be consumed or destroyed by the sun when it becomes a red giant, along with Earth.
teh Universe’s End: What Does the Latest Research Say?
is the universe Really Going to End Sooner Than We Thought?
Yes, according to recent research.Scientists have revised their estimates for the universe’s demise. While the end is still incredibly far off,the timeframe has been shortened.
what is the New Timeline for the Universe’s Demise?
The projected timeframe for the disintegration of the last white dwarfs is now estimated to be approximately 10 to the power of 78 years. This is a important change from the previous estimate.
How Does This Compare to Previous Estimates?
The earlier estimate for the universe’s end was 10 to the power of 1,100 years. The new calculation represents a considerable acceleration, although both figures remain incredibly long timescales.
What is a White Dwarf, and Why is its Fate Critically important?
White dwarfs are the dense remnants of dead stars, similar to what our Sun will eventually become. Studying their eventual disintegration helps scientists understand the universe’s overall evolution and, ultimately, its end.
What Study Revised these Calculations?
The updated timeline is based on a study published in May 2025 in the journal Cosmology and Astroparticle Physics. A team of Dutch scientists at Radboud University conducted this research.
What Inspired the Dutch Team’s Research?
The Dutch scientists re-evaluated existing calculations based on the theoretical work of Stephen Hawking, a British physicist. Thay focused on how white dwarfs eventually dissolve, utilizing Hawking’s theory of black hole evaporation.
What is Hawking’s Theory of Black Hole Evaporation?
Hawking’s theory posits that black holes emit radiation, leading to a gradual loss of mass and, eventually, their disappearance. This radiation, often called Hawking radiation, is emitted near the event horizon – the point of no return around a black hole – and causes particles to escape, leading to the hole’s eventual shrinking.
How Did the Researchers Apply Hawking’s Theory to White Dwarfs?
The Dutch team explored how Hawking’s radiation might affect white dwarfs,which can persist for billions of years,leading to their eventual dissolution. The rate of evaporation is directly related to an object’s density.
What Will Happen to Earth, the Sun, and the Moon?
The earth, the Sun, and the moon will have long ceased to exist long before the predicted end of the universe. In fact, the timeline of events is as follows:
- Earth: Will become uninhabitable within 1 to 3 billion years due to rising temperatures.
- Sun: Will expand into a red giant around 5 billion years from now,likely engulfing or destroying Earth. Afterward (6-7 billion years), the Sun will transform into a white dwarf.
- Moon: Will either be destroyed by the sun when it becomes a red giant or take approximately 10 to the power of 89 years to evaporate.
How Will the Sun Eventually Die?
The sun will eventually evolve into a red giant. During this phase, it will expand dramatically, perhaps engulfing the inner planets, including Earth. After its red giant phase, the sun will shrink and cool, becoming a white dwarf.
Can the Moon Evaporate?
Theoretically, yes, the moon could evaporate through a process similar to Hawking radiation, but that would take roughly 10 to the power of 89 years. However, its more probable fate is to get consumed or destroyed by the sun when it expands into a red giant.
What is the Moon’s Current Movement?
The moon is slowly drifting away from Earth at a rate of about 4 centimeters per year.
How Does the Density of an Object Affect Its Evaporation Rate?
The rate of evaporation for any object is directly related to its density. Denser objects take longer to evaporate.

What are the Researchers Hoping to Learn?
The goal of this research is to better understand physical theories by examining extreme scenarios, such as Hawking radiation’s effect on white dwarfs. Scientists hope that this research may one day help unravel the mysteries of these concepts.
Summary of Timelines: key Events
Here’s a rapid summary of the key milestones and estimates discussed in the article:
| Event | Estimated Timeframe | Details |
|---|---|---|
| Earth Uninhabitable | 1 to 3 billion years | Rising temperatures, oceans boil away. |
| Sun Becomes Red Giant | around 5 billion years | Likely engulfs Earth. |
| Sun Transforms into White Dwarf | 6 to 7 billion years | Small, dense, and extremely hot star. |
| Moon Evaporates (Theoretical) | 10 to the power of 89 years | via Hawking radiation (highly unlikely). |
| White Dwarf Disintegration (New Estimate) | 10 to the power of 78 years | Revised estimate for the end of white dwarfs,which means the end of the universe |
